Sahih Bukhari Volume 2, Book 25, Hadith 1665

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا عَمْرٌو، حَدَّثَنَا مُحَمَّدُ بْنُ جُبَيْرِ بْنِ مُطْعِمٍ، عَنْ أَبِيهِ، كُنْتُ أَطْلُبُ بَعِيرًا لِي‏.‏ وَحَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، سَمِعَ مُحَمَّدَ بْنَ جُبَيْرٍ، عَنْ أَبِيهِ، جُبَيْرِ بْنِ مُطْعِمٍ قَالَ أَضْلَلْتُ بَعِيرًا لِي، فَذَهَبْتُ أَطْلُبُهُ يَوْمَ عَرَفَةَ، فَرَأَيْتُ النَّبِيَّ صلى الله عليه وسلم وَاقِفًا بِعَرَفَةَ، فَقُلْتُ هَذَا وَاللَّهِ مِنَ الْحُمْسِ فَمَا شَأْنُهُ هَا هُنَا

Narrated By Muhammad bin Jubair bin Mut'im : My father said, "(Before Islam) I was looking for my camel..." The same narration is told by a different sub-narrator. Jubair bin Mut'im said, "My camel was lost and I went out in search of it on the day of 'Arafat, and I saw the Prophet standing in 'Arafat. I said to myself: By Allah he is from the Hums (literally: strictly religious, Quraish were called so, as they used to say, 'We are the people of Allah we shall not go out of the sanctuary). What has brought him here?"
